PP mat on e 1 i specimens //i f To all whom it may concern:

Be it known that 1, JAMES E. SUMMERS, acitizen of the United States, residing at Lynchburg, in the county of Campbell and State 5 of Virginia, haveinvented certain new and useful Improvements in Artificial Marble or Stone, of which the following is a full, clear, and exact description.

My invention relates, first, to a liquid composition which when mixed with certain cementing substances, hereinafter specified, in a pulverized or granular condition shall be hardened and solidified to such a degree that the resulting product shall be capable of use as an artificial marble or stone and closely resemble those minerals as to grades of quality, finish, color, &c.

My invention relates, further, to a composition or body including as an ingredient the said liquid mixed with said solid materials.

In carrying out the first part of my invention-that is to say, the preparation of the liquid composition mentioned-1 take the following ingredients and mix them in substantially the proportions and manner hereinafafter specified, to wit: to ten (10) gallons of milk of lime I add one-half G) pound of glycerin, six ((3) ounces of silicat one- Ilalf (1}) pou nd of common see ,two (2) pounds of com on salt and onea f (s) pound of ground narshmallow-root. These ingredients are p aced in a suita le vessel and boiled and stirred together until they combine, after which the preparation is run through a sieve.

It is then ready for use.

In carrying out the second part of my invention, involving the use of the said liquid preparation with the solid materials,and in order to make artificial marble or stone, I take 0 h draulic cement, gypsum, or any of the solids used 1n the arts for'such purposes and reduce them t apulverulent or granular condition. I then mix with said granulated materials a sufficient quantity of my said liquid composition to form a plastic mass of such consistency as to en able it to be easily molded by hand or to be placed in molds to form or cast such articles as may be desired. The necessary colors or tints maybe added to the mass, preferably while it is being kneaded, should it be desired to have the resulting body colored or tinted throughout, or the color or tint may be applied to the surface only.

I do not limit myself to the use of the particular solid matters above mentioned, as any 5 5 material calculated to produce the desired result when mixed with the liquid composition specified may be employed. The said liquid composition will give strength and hardness to any concrete substance formed of particles that have been mixed therewith and packed together while the mass is in a plastic state.

Having thus described my invention, I claim 1. A composition of matter, consisting of milk of lime, glycerin, silicate of soda, soap, salt and ground marshmallow-root, as set forth.

2. A composition of matter, consisting of the herein-mentioned ingredients inpropor- 7o tions substantially as follows, to Wit: ten gallons of milk of lime, one-half pound of glycerin, six ounces of silicate of soda, one-half pound of soap, two pounds of salt, and onehalf pound of ground marshmallow-root, as set forth.

3. A composition of matter consisting of a solution composed of milk of lime, glycerin, silicate of soda, soap, salt, and marshmallowroot, in proportions substantially as specified, combined with a cementing substance in granular form, as set forth.

4. An artificial stone or marble consisting of a cementing substance, and a liquid compound of milk of lime, glycerin, silicate 'of soda, soap, salt, and marshmallow-root,in or about the proportions specified, as set forth.

In testimony whereof I hereunto set my hand.

JAMES E. SUMMERS.
